What is destroying kelp?
A dramatic outbreak of kelp-eating purple sea urchins along the Central Coast of California in 2014, leading to a significant reduction in the region's kelp forests, was driven primarily by the emergence of sea urchins from their hiding places rather than an increase in the urchin population.
Does kelp clean the ocean?
They store carbon in their photosynthesising fronds, and their wave-buffering bodies are the surest defence some coastlines have against violent storms. They also clean up our waste: kelps can rapidly absorb nutrient pollution caused by fertilizers running off from farmland into the sea.
Does kelp help climate change?
Seaweed has been removing carbon dioxide from the atmosphere for at least 500 million years. Recent studies suggest that wild seaweed continues to do humanity a solid by sequestering 173 million metric tons annually. The average square kilometer of seaweed can sequester more than a thousand metric tons.

Why is iodine important for the body?
Iodine is essential for the production of thyroid hormones. These hormones affect every cell in the body and play a number of key roles including regulating metabolism, influencing how fast calories are burned and how fast food moves through your digestive tract; raising and lowering body temperature, and other actions. They also have an important role in fetal and infant development. Not consuming enough iodine can lead to metabolism issues and goiter, the enlargement of the thyroid gland. (3, 5)
Where does kelp grow?
Kelp is a type of seaweed that grows in kelp forests in the ocean. Kelp forests are important habitats for a variety of marine life. They usually grow along rocky coastlines, and kelp has anchors that allow it to hold on to rocks. It then grows up toward the water’s surface, so it can get enough sunlight to thrive. (1, 2)

What animals eat kelp?
Reed said that one of the researchers, Jenny Dugan, is looking into how the amount of kelp found along the beach affects shore bird populations. Crustaceans, beach flies, and other insects feed off of kelp washed ashore. After digesting it, they release nitrogen into the sand, which is then washed back out to sea.
Is kelp a plague?
While some people see kelp as smelly, irritating detritus deposited on beaches as a plague to their enjoyment, this seaweed has an important role in our ecosystem. UCSB researchers have secured a renewed round of National Science Foundation funding to take a long-term look at the interaction between the coastal kelp forests and activities occurring on land and in the offshore ocean.
Is kelp dead or alive?
While dead kelp might not be aesthetically pleasing to everyone, it is left to decay naturally along the beaches in Isla Vista, providing a draw for shore birds, such as the Snowy Plover. In contrast, the kelp is removed from some beaches in the Santa Barbara area, particularly in tourist areas.
Is kelp die off bad?
Reed said that a certain amount of kelp bed die-off isn’t a bad thing. Kelp beds can become overgrown, and may not allow enough sunlight through the canopy to promote a diversity of food production on the bottom. However, unusually large waves or an increase in ocean temperature may cause unusually large die-offs that are not beneficial.
